Formula and Step-by-Step

teaspoons × 2.38g/tsp = grams
  1. Start with 18 teaspoons of pecans
  2. 1 teaspoon of pecans = 2.38g
  3. 18 × 2.38 = 42.75g

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Chopped, sliced, and whole pecans have very different weights per measuring spoon. Always match the form specified in your recipe.

Understanding the Units

What is a Teaspoon?

A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.

What is a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

Frequently Asked Questions

About 42.75 g, based on pecans having a density of 114g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 2.38 (grams per teaspoon for pecans). For 18 teaspoons: 18 × 2.38 = 42.75 g.
For the most accurate results, weigh pecans on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 42.75 g ÷ 2.38 = 18 teaspoons. Or use the Grams to Teaspoons converter.
